BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a portable electronic apparatus having an external connector fixed at an internal circuit board, and more particularly to an electronic apparatus having a connector suitable to an ultra-thin product for providing an electrical connection for a data communication.

[0003] 2. Description of the Background Art

[0004] Generally, electric apparatuses includes a circuit board (PCB) in its main body to perform various functions and a connector fixed by soldering at the circuit board to connect a cable such as a LAN or a MODEM.

[0005] U.S. Pat. Nos. 4,978,317 and 5,613,873 disclose a technique related to such a connector, and FIG. 1 is a perspective view of a partial section of a connector presented in the U.S. Pat. No. 4,978,317.

[0006] With reference to FIG. 1, a connector 1 includes a housing 3 in a rectangular shape contouring the outer case and a plug inserting portion 5 to which a plug (not shown) of a cable is inserted for a connection.

[0007] A plurality of conductors 7 are formed at a portion of inner side of the plug inserting portion 5 for electric connection with the plug. The connectors 7 penetrate the housing 3 from one inner side of the plug inserting portion 5, so that connection leads 7 a are protrusively formed at one face (upper side in FIG. 1).

[0008] The connection leads 7 a protrusively formed at one face of the housing 3 are inserted into holes formed at the circuit board (PCB) to be protruded to the other side of the circuit board. The protruded connection leads 7 a and a circuit pattern formed on the circuit board (PCB) are soldered to thereby connect the circuit board (PCB) and the connector 1.

[0009] The connector 1 further includes an LED 9 for displaying a transmission state of a signal transmitted according to a connection between the connector 1 and the plug. The LED 9 is installed exposed in parallel at one side, that is, at the side where the plug inserting portion 5 is formed. The terminals 9 a of the LED 9 are protrusively formed at the same face where the conductors 7 are protruded, so as to be inserted into the holes of the circuit board (PCB) and fixedly connected by soldering, like the connection leads 7 a.

[0010] However, the conventional connector constructed as described has the following problems.

[0011] That is, being used to connect the circuit board and an external product, the connector maintains an interface as the terminals protruded at one face of the housing are directly soldered or mounted on an upper surface of the circuit board.

[0012] However, in the above structure, referring to the height of the product, the connector is positioned on the upper surface of the circuit board, requiring an installation space in consideration of the thickness and the height of the circuit board (PCB) itself.

[0013] In addition, an installation space is required according to the height of various components attached on the under surface of the circuit board, and besides, a space is also required to prevent an electric short between elements.

[0014] Due to these factors, the conventional connector has many problems.

[0015] For example, first, it is hardly adoptable to a ultra-thin product such as a super-thin lap-top computer which is restricted in its height.

[0016] Secondly, since the exposing hole is formed only at one side of the main body to expose the plug inserting portion of the connector outwardly, it is difficult to reduce the whole thickness of the main body.

[0017] Thirdly, as the connector is fixed at the circuit board (PCB) by the connection leads 7 a and 9 a, the fixed state of the connector is not reliable, so that when the connection operation of the plug is repeatedly performed, the soldering between connection leads and the circuit pattern of the circuit board (PCB) is damaged, causing a opening phenomenon. In case of a few number of the connection leads, the housing is made enlarged to obtain a large contact area with respect to the circuit board, which, however, results in the enlargement of the connector against the intention to obtain a compact size product.

[0018] Fourthly, the connecting wires are used to connect the connection leads and the circuit board. In such a case, the connection leads can be processed by clamping, but the connection leads of the two LEDs should be directly soldered with the wire. In addition, in a specific case, more than two wires should be simultaneously clamped or soldered with one connection leads, there occur many defectives. As a wire becomes defective, it is not possibly reused, causing an increase in a unit cost.

[0019] Fifthly, in case of using the dip-soldering type connector, an interface cable to be connected to a LAN card (3 Combo, Intel Combo, X-Combo) and a connector are additionally required, causing an increase in the number of components.

[0020] The above references are incorporated by reference herein where appropriate for appropriate teachings of additional or alternative details, features and/or technical background.

[0047] The first rear face 109 and the second rear face 110 are formed by being successively extended from the first side face 107 and the second side face 108. As the first rear face 109 of the upper case 103 and the second rear face 110 of the lower case 104 are combined, the rear side is formed.

[0048] A plurality of connection ports are installed at the rear side so as to be connected with an external instrument.

[0049] The connectors include a power connection port 122, a parallel port 123, a serial port 124, a video port 125, a keyboard port 126 and a mouse port 127, a LAN connecting connector 128 and a modem port 129. These connectors are connected to the circuit board 90 installed inside the body 101.

[0050] Referring to FIG. 3, the screen display unit 102 is rotatably installed at a hinge unit 114 formed at both sides of the rear end of the body 101, forming a closed state as shown in FIG. 2 and an opened state as shown in FIG. 3.

[0051] The structure of the screen display unit 102 includes a very thin rectangular body 115 consisting of a rectangular case 117 metal plated for shielding at its inner surface and connected to the hinge unit 114, a liquid crystal display device 118 fixedly installed in the case 117 and a cover 116 combined with the case 117, covering the outer marginal portion of the display device 118 with its central portion exposed.

[0052] The display device 118 is connected to the circuit board 90 installed in the body 101 by a flexible printed circuit (FPC) (not shown).

[0053] The upper case 103 of the body 101 has an upper face 111 formed bent successively at the end portion of the first side face 107 and the first front face 105 from the upper portion, and a key board unit 112 having a plurality of keys 113 are detachably installed at the upper face 111.

[0054] The construction of the connector which connected a LAN or a modem cable adopted to a ultra-thin lap-top computer 100, a portable electronic apparatus, having an external connection connector fixed at the internal PCB.

[0055] First, LAN connection connector 20 is shown in FIG. 5.

[0056] A housing constructing the connector 20 has a rectangular parallelepiped shape. A plug inserting portion 32 is formed at the front wall 30 a of the housing 30, into which a plug (not shown) of LAN or a modem cable is inserted.

[0057] At the upper wall 30 c of the housing 30, an LED receiving groove 34 is formed long from the front wall 30 a of the housing 30 to the rear wall 30 b. An LED opening and supporting portion 34 a is formed to be made small at a portion where it approaches the front face 30 a of the receiving groove 34.

[0058] Two LED receiving grooves 34 formed in parallel at the left side 30 e and right side 30 f. A cut-out portion 36 connected to the LED receiving groove 34 from the left side wall 30 e of the housing 30 to the right side wall 30 f, that is, across the direction in which the LED receiving groove 34, is formed at a lower stage than the part of LED receiving groove 34 at the rear end of the housing 30.

[0059] A connection terminal 40 is installed for electrical connection with the plug (not shown) in the plug inserting portion 32 of the housing 30.

[0060] The connection terminal 40 penetrates the inner side of the lower wall 30 d of the housing and bent by 90° toward the upper face 30 c so that its one end portion (a connection lead) 40 a is protrusively formed to an upper surface 36 a of the cut-out portion 36.

[0061] The connection terminal 40 is slanted at a predetermined angle inwardly in the plug inserting portion 32, so that when the plug (not shown) is inserted, the connection terminal 40 is elastically deformed and tightly combined to the terminal of the plug.

[0062] The connection terminal 40 is formed by plural numbers such as 4, 6 and 8 ones depending on a type of a connector, that is, a communication module.

[0063] The connection terminal 40 is inserted to be integrally formed with the housing 30 when the housing 30 is molded in an insert-molding method.

[0064] The LEDs 45 are installed in the housing 30 to display the connection state and the operation state with respect to the plug (not shown). The front end of the LED 45 is positioned at the front end of the LED receiving groove 34, that is, at the LED opening and supporting portion 34 a at the side of the front wall 30 a, so that it can be viewed from the front face of the housing 30.

[0065] The LED opening and supporting portion 34 a is formed a bit smaller that the front end of the LED 45 so that when the front end of the LED 45 is inserted into the LED opening and supporting portion 34 a, the front end of the LED 45 is firmly fixed to the LED opening and supporting portion 34 a.

[0066] The LED terminal 45 a formed at the rear end of the LED 45 is extended to the rear wall 30 b of the housing 30 within the LED receiving groove 34 and the end portion thereof is protruded to the front surface 36 b of the cut-out portion 36.

[0067] In order to block an electronic wave from flowing to the lower wall 30 d of the housing 30, a shielding plate 70 is mounted to integrally cover the front wall 30 a and the upper wall 30 c.

[0068] The shielding plate 70 contacts the lower case 104 in view of improvement of an EMI performance.

[0069] A shielding end portion 70 a is protrusively formed to the front surface 36 b of the cut-out portion 36 at the end of the shielding plate 70. The upper surface of the shielding plate 70 supports the LED 45 installed at the LED receiving groove 34 of the housing 30 upwardly to prevent the LED 45 from releasing.

[0070] With reference to FIG. 6, a flexible cable 60 b is installed including a flexible cable 60 a for a circuit board LAN cable and a flexible cable 60 b for a docking LAN cable which are integrally formed.

[0071] The flexible cable 60 a for a circuit board LAN cable serves to transmit a signal between the connector 20 and the circuit board 90, and the flexible cable 60 b for a docking LAN cable serves to transmit a signal between the connector 20 and a docking system (not shown). One end portion 40 a of the connection terminal 40, the LED terminal 45 a of the LED 45, the shield terminal 70 a of the shielding plate and a pad 61 of the flexible printed circuit 60 are connected by soldering to the flexible printed circuit 60, to transmit a signal.

[0072] With reference back to FIG. 5, a reinforcement film 50 is fixedly attached at the bottom surface of the pad 61 of the flexible printed circuit 60 at a distance from the tip 62 of the pad 61, and the tip 62 of the pad 61 is readily bent without the reinforcement film 50.

[0073] The pad 61 is tightly attached on the upper surface 36 a of the cut-out portion 36, so that the end portion 40 a of the connection terminal 40 exposed on the upper surface 36 a penetrates the pad 61, so as to be exposed, and the connection end portion 40 a and a circuit pattern of the flexible printed circuit 60 are connected by soldering.

[0074] Thereafter, the tip 62 of the pad 61 is bent to be tightly attached on the front surface 36 b of the cut-out portion 36, so that the LED terminal 45 a and the shield terminal 70 a of the shielding plate penetrate the tip 62 of the pad 61 and is exposed. The exposed LED terminal 45 a and the shield terminal 70 a of the shielding plate are connected with the circuit pattern of the flexible printed board 60 by soldering.

[0075] With reference to FIGS. 7 and 9, a connector 65, a connecting member for connection with the circuit board 90, is provided at the other end of the opposite side of the flexible cable 60 a for a circuit board LAN cable connected with the housing 30. And, various components 63 for the prevention of an electromagnetic interference (EMI) such as an EMI filter conventionally used as being installed on the circuit board 90 are installed on the flexible printed circuit 60.

[0076] Two fixing pieces 80 and 80′ are protrusively formed at predetermined positions of both side walls 30 e and 30 f of the housing 30 to fix the connector 20 at the circuit board 90.

[0077] The fixing pieces 80 and 80′ are formed at about the middle position of the side walls 30 e and 30 f, somewhat inclined to the front wall 30 a.

[0078] Engaging holes 82 and 82′ are formed at the center of the fixing pieces 80 and 80′, and the position of the fixing pieces 80 and 80′ may be suitably varied according to a designing condition.

[0079] As shown in FIG. 7, the connector 20 is mounted at the circuit board 90. Various components for functions, including components for connection with the connector 20, are mounted at the circuit board 90.

[0080] A receiving portion 92 is formed at one end portion of the circuit board 90 to receive the connector 20. The receiving portion 92 is formed by cutting out one rear end portion of the circuit board 90, in which the housing 30 of the connector 20 is mounted.

[0081] Engaging holes 94 and 94′ are formed at positions at both end portions of the circuit board 90 corresponding to the engaging holes 82 and 82′ of the fixing pieces 80 and 80′ installed at both ends of the housing 30.

[0082] Mounting operation of the connector 20 having the construction as described above will now be explained.

[0083] The connector 20 forms a cut-out portion 36 is formed-at the upper portion of the rear end of the housing 30, so that every connection ends 40 a, 45 a and 70 a to be connected from the connector 20 to the circuit board 90 are protrusively formed at the cut-out portion 36. Thus, each terminal is positioned in the cut-out portion 36 without being protruded to the surface of the upper wall 30 c and the rear wall 30 b of the housing 30.

[0084] The connector 20 is mounted at the circuit board 90. As shown in FIG. 7, the housing 30 is mounted at the receiving portion 92 formed at the circuit board 90. At this time, the engaging holes 82 and 82′ of the fixing pieces 80 and 80′ formed at the left and right outer faces of the housing 30 comes in contact with the corresponding engaging holes 94 and 94′ formed at the circuit board 90, and a screw 95 is suitably inserted between the engaging holes 82, 82′, 94 and 94′.

[0085] Accordingly, the rear wall 30 b of the housing 30 penetrates the receiving portion 92 and is positioned below the circuit board 90, and the circuit board 90 is positioned at about the middle portion of the housing 30, which may be different according to the height of the fixing pieces 80 and 80′ formed at the housing, though.

[0086] Next, the connector 65 of the flexible cable 60 a for a circuit board LAN cable is connected to a connecting unit 64 of the circuit board 90, and then, one end of the flexible cable 60 b of for a docking LAN cable is connected with the connector 66 for a docking system, thereby completing mounting of the connector 20.

[0087]FIGS. 8 and 9 are drawings illustrating a dual-type connector 200 in which a modem connector 129 are integrally formed with the connector 20 in accordance with another embodiment of the present invention.

[0088] The dual-type connector 200 is so constructed that a modem connector 129 is integrally formed at the right side wall 30 f of the LAN connecting connector and fixing pieces 82 and 82′ are formed at the left side wall 30 e of the LAN connecting connector 128 and at the right side face 202 of the modem connector 129.

[0089] A first opening 131 and a second opening 131′ are formed at the second rear face 110 of the lower case 104 of the body 101 in a manner of exposing the plug inserting portion 32 of the dual-type connector 200. A protrusion 133 is formed between the two openings 131 and 131′. Supporting bosses 96 and 96′ are protruded upwardly at the position corresponding to the engaging holes 94 and 94′ of the circuit board 90.

[0090] A third opening 130, a fourth opening 130′ and a protrusion 132 are formed at the first rear face 109 of the upper case 103 corresponding to the openings 131 and 131′ and the protrusion 133.

[0091] And, a connecting modem cable 210 is engaged at the rear end of the modem connector 129.

[0092] After the circuit board 90 is positioned inside the lower case 104, when the lower wall of the dual type connector 200 is inserted in the receiving portion 92, the fixing pieces 80 and 80′ formed at both side walls of the dual-type connector 200 contact with the upper face of the circuit board 90, supporting the installation of the connector.

[0093] Thereafter, the screw 95, an engaging member, penetrates the engaging holes 82 and 82′ of the fixing pieces 80 and 80′ and the engaging holes 94 and 94′, to be fixed at the supporting bosses 96 and 96′ of the lower case 104. Accordingly, the circuit board 90 and the connector 200 are simultaneously fixed.

[0094] Besides the dual type connector 200, such fixing structure is adopted in the same manner even in case where the LAN connecting connector 20 is solely used.

[0095] The operational effects of the connector of the present invention are as follows.

[0096] As so far described, since the connector is positioned penetrating the receiving portion formed at the circuit board, the connector may be positioned at about the middle position of the connector, to make the whole product thin.

[0097] In addition, as state above, in case where a flexible printed circuit is used to connect the connector and the circuit board, the plurality of terminals included in the connector can be connected simply with the circuit board and interference with other components can be minimized.

[0098] Especially, since the cut-out portion is formed at the housing so that various terminals are not protruded outwardly of the housing, the height of the connector is reduced to be thin, and thus, it can be adopted to a ultra-thin product.

[0099] In addition, since the connector is engaged at the circuit board by using an additional engaging member, the connector is firmly supported. Thus, in spite of frequent occurrence of connection, it can be stably connected with the circuit board.

[0100] Moreover, since the connector and the circuit board are fixed at the lower case by one-time engaging operation, its productivity can be increased.

[0101] Furthermore, since the flexible printed circuit (FPC) is used, a bead or a capacitor, components for preventing the electromagnetic interference (EMI) such as the EMI filter which has been installed for use on the circuit board, can be mounted on the flexible printed circuit, spatial utilization on the circuit board is increased and the performance of the EMI is remarkably improved.

[0102] Also, since the shielding plate integrally formed at the upper face and the front face of the connector comes in contact with the bottom case of a main body of a computer, the performance of the EMI is more enhanced.

[0103] In addition, for a connection, the flexible printed circuit is used, rather than the clamping as in the conventional art, so that the connection is simplified, resulting in an effect that defective is considerably reduced.

[0104] Moreover, since each terminal is directly soldered to the flexible printed board and even a combo card is connected by cable, the production process is reduced and the productivity is much enhanced.

[0105] Furthermore, since the upper end portion of the connector is opened, the LED can be easily inserted thereto. Also, when the LED and the connection terminal of the LED are defective, they can be easily replaced by parts. Thus, compared to the in-mold type connector, the unit cost can be reduced.

[0106] The foregoing embodiments and advantages are merely exemplary and are not to be construed as limiting the present invention. The present teaching can be readily applied to other types of apparatuses. The description of the present invention is intended to be illustrative, and not to limit the scope of the claims.
